After connecting the
network, the received
optical power of the optical
contact point is unstable
and has large continuous
change. The output RF
signal is unstable, too. But
the detected output optical
power of the optical
transmitter is normal.
The optical fiber active connector
types do not match, maybe the APC
type connect to PC type, make the
optical signal cannot normal
transmission.
The optical fiber active connector or
adapter may be polluted seriously or
the adapter has been damaged.
1. Check the type of optical fiber active
connector and adopt the APC type optical
fiber active connector to ensure the normal
transmission of optical signal.
2. Clean the polluted optical fiber active
connector or adapter. Specific operation
methods see “Clean and maintenance method
of the optical fiber active connector”.
3. Replace the damaged adapter.
10. Clean and maintenance method of the optical fiber active connector
In many times, we consider the decline of the optical power as the equipment faults, but
actually it may be caused by that the optical fiber connector was polluted by dust or dirt. Inspect the
fiber connector, component, or bulkhead with a fiberscope. If the connector is dirty, clean it with a
cleaning technique following these steps:
1.
Turn off the device power supply and carefully pull off the optical fiber connector from the
adapter.
2.
Wash carefully with good quality lens wiping paper and medical absorbent alcohol cotton. If
use the medical absorbent alcohol cotton, still need to wait 1~2 minutes after wash, let the
connector surface dry in the air.
3.
Cleaned optical connector should be connected to optical power meter to measure output
optical power to affirm whether it has been cleaned up.
4.
When connect the cleaned optical connector back to adapter, should notice to make force
appropriate to avoid china tube in the adapter crack.
5.
The optical fiber connector should be cleaned in pairs. If optical power is on the low side after
clean, the adapter may be polluted, clean it. (Note: Adapter should be carefully operated, so as
to avoid hurting inside fiber.
6.
Use compressed air or degrease alcohol cotton to wash the adapter carefully. When use
compressed air, the muzzle aims at china tube of the adapter, clean the china tube with
compressed air. When use degrease alcohol cotton, insert directions need be consistent,
otherwise can’t reach a good clean effect.
